  • the national identification numbers from the national directory of natural persons (13-digit identification number, without spaces);
  • or the national identification numbers of legal person (11-digit identification number, without spaces).

Statements sent in paper format to the ACD will no longer be accepted.

The original tax cards must be kept like all other commercial documents for 10 years, in accordance with company law.

  • the IT division of the ACD for technical questions regarding the document in XML format;
  • for questions regarding taxation, the competent RTS tax office: RTS 1 (Centre), RTS Esch-sur-Alzette (Sud) or RTS Ettelbruck (Nord).

Conditions of transmission

The transmission of statements must:

  • have a unique reference file number per tax year and debtor;
  • contain at least one extract of a salary or pension statement;
  • refer to only one tax year;
  • only contain the statements from one debtor (same number of identification).

Salary and pension data transmissions may:

  • contain the extracts for different employees or retirees of the same debtor (employer);
  • contain initial extracts for salaries and pension contributions as well as annulling extracts.

Account statements must have a unique reference number per tax year and debtor. The time periods in the statements must correspond to the tax year.

In the event that the beneficiary changes his country of residence during the year, it is necessary to create 2 separate statements.
